I had one of the Camry's that had the oil consumption problem to the point where it burned a quart of oil in under two hundred miles. Toyota fixed it at around 144,000 miles and the spark plugs were replaced and fouled many times. This p0420 code has come on and off with misfire codes prior to the piston ring repair, but now it is only p0420. I tried the temperature test and the top came up about a hundred to hundred fifty degree higher difference from the bottom, but my newer Camry had similar results. On the scanner tool, 02 sensor one says the volts are around 3.200 up and down. 02 #2 takes a while but fluctuates around.4 area. On my newer Camry, same for #1, #2 did not go above.000. I really hate to buy a catalytic converter for $400.00 (plus) if it is a sensor. Any ideas before I go nuts and end up taking it somewhere instead of fixing it myself?
have the same problem?
